Mini Pressure Compensation Seals (PCS) Including Service – from a Single Source
Pressure Compensation in Miniature Design
Oberschleissheim, June 6, 2015 – Even the smallest elements and components in
technical industries and the automotive sector have a housing that needs to be
reliably ventilated. Schreiner ProTech produces Mini Pressure Compensation
Seals (PCS) with a diameter of 3 or 4 mm that seal housing openings, thus
preventing the entry of water and dust. At the same time Schreiner Services
offers a system for process-reliable application tailored to specific customer
requirements.
Control units, PCB connections or filters: there is a clear trend towards "small and
lightweight", especially when it comes to motor vehicle production. Schreiner ProTech
responds to this development in the automotive industry with Mini Pressure
Compensation Seals (PCS) that perfectly protect small component openings. PCSs are
self-adhesive, air-permeable membranes which are precisely adapted to the individual
substrate. Water, oil and fuel simply roll off their surface.
Mini PCSs, for instance, are applied for pressure transducers used in engines, brake
systems or pneumatic units. Other sensors measure humidity, temperature fluctuations
or the distance to other road users. The sensitive components are subjected to rough
environmental influences which put them under exceptional stress. Especially
electronics must be protected against rain, splashes of water, oil and salt while
continuous ventilation ensures pressure compensation. The small yet powerful Mini
PCSs meet all technical requirements for ventilating sensor electronics and providing
protection against external influences.
Challenges posed by miniaturization
The miniaturization of Pressure Compensation Seals requires significantly higher
process reliability when the PCS is applied to the sensor, since the tolerances for exact
positioning are considerably smaller. In order to leave the ventilation hole completely
open the maximum positioning tolerance must not exceed ± 0.2 mm – and all of that
with a PCS diameter of 3 mm. For process-reliable application to components Schreiner
ProTech and Schreiner Services offer an application system that is perfectly tailored to
Mini PCSs and all process parameters and can be integrated into fully automated

manufacturing lines for large quantities and multi-shift operation. The application system
features a special centering unit. Contact pressure of the membrane is solved
separately. All processes are controlled by a Siemens S7 control unit. Contact pressure
during application and duration of pressure can be precisely adjusted throughout
processing. In addition, both parameters are closely monitored by the system. "Another
great advantage for application in continuous operation is the robust design of the entire
dispensing unit" explains Annette Barth, Product Manager at Schreiner ProTech.
